initialData should also receive queryKey as parameter

[mydesweb]

same as queryFn, just keep the same pattern.

what do you need the key for ?

[mydesweb]

To fetch initial data from my local storage custom implementation. I prefer to use a single function same as queryFn and share the same logic.

Have you tried the persister option ?

[mydesweb]

Sure, I prefer to use my own logic for much more flexibility.
For the moment I use something like this to fetch initialData stored in my local db.

const useQuery = <T>({ queryKey }: Config) => {
  const storageKey = "query." + queryKey.join(".");
  return useTanStackQuery<T>({
    queryKey,
    queryFn: queryFn<T>(storageKey),
    initialData: initialData<T>(storageKey),
    initialDataUpdatedAt: initialDataUpdatedAt(storageKey),
  });
};
